How can I get the length of a JSON Array I get using json.net in C#? After sending a SOAP call I get a JSON string as answer, I use json.net to parse it.
Example of the json I got:
{"JSONObject": [
{"Id":"ThisIsMyId","Value":"ThisIsMyValue"},
{"Id":"ThisIsMyId2","Value":"ThisIsMyValue2"}
]}
And I parse it and write it in console:
var test = JObject.Parse (json);
Console.WriteLine ("Id: {0} Value: {1}", (string)test["JSONObject"][0]["Id"], (string)test["JSONObject"][0]["Value"]);
This works like a spell, only I don't know the length of the JSONObject, but I need to do it in a for loop. I only have no idea how I can get the length of test["JSONObject"]
But something like test["JSONObject"].Length would be too easy I guess :(..

You can cast the object to a JArray and then use the Count property, like so:
JArray items = (JArray)test["JSONObject"];
int length = items.Count;
You can then loop the items as follows:
for (int i = 0; i < items.Count; i++)
{
var item = (JObject)items[i];
//do something with item
}
According to Onno (OP), you can also use the following:
int length = test["JSONObject"].Count();
However, I have not personally confirmed that this will work
